COMPANY, OF MILWAUKEE, wIsooNs me I WISCONSIN, ASSIGNOR To oHAIn BELT IN, A CORPORATION OFVWISGONSIN- J AGITATING ATTACHMENT FOR VEHICLE BODIES Application filed April 20,

Thisinvention relates to agitating attachments for vehicle bodies and has for one of its objects to provide a deviceof this character which will be simple in construction, com- 5 paratively inexpensive to manufacture, and more efficient in use than those which have been heretofore proposed.

' A further object of the invention is to provide a simple andv effective means which may 19 be readily attached to and detached from the body of a standard motor truck or other similar vehicle, and which may be employed for'the agitation of premixed concrete or other similar materials. 1

15 With the above and other objects in view,

' which will appear as this description proceeds, the invention consists in the novel details of construction and combinations of parts more fully hereinafter described and particularly pointed out in the appended claims.

Referring to the accompanying drawings forming a. part of this specification in which like reference characters designate like parts 95 in all of the views Figure 1 is a side elevational view, partly broken away, of a motor vehicle with an agitating attachment constructed in accordance with the present invention in place thereon;

Figure 2 is a top plan view of the truck body and agitating attachment shown in Fi 1' 1 Figiire 3 is a transverse sectional view taken approximatel on the plane indicated 35 by the line 33 of Fig. 1 looking in the direction of the arrows;

Figure 4 is a View similar to Fig. 3 andv taken on substantially the same plane but looking in the opposite direction; and

Figure 5 is a detail side elevational view of the agitator detached from the body.

Referring more particularly to said drawings, numeral 10 indicates generally a motor vehicle such as a motor truckhaving a chassis 4511 upon which is mounted the load-receiving 1929. Serial No. 356,765.

body 12 which may be of metal orother. suit-. able construction. The said body maybe of the well known dumping type provided with a pivotal tail gate 13 adapted to be elevated for dumping by means of a suitable power or hand driven hoist 14. i I V, In present day concrete practice it has be come quite common to mix the concrete at'a central plant, which is conveniently located as to transportation facilities for the raw materials, and to then transport the mixed con crete to the point of use in motor trucks or other similar vehicles. It has been found, however, that during suchtransportation the concrete materials have a tendency to separate, with the heavier aggregates settling to the bottom and the Water andcement floating above them.

To overcome this objection numerous means have been proposed for continuously agitating the mixed concrete during transit whereby the separation of the materials isv prevented. Most of the apparatus heretofore proposed has contemplated the provision of special bodies or vehicles for Which special means are a considerable eX- pense to the contractor who as a rule already owns one or more motor trucks. The present invention provides an attachment for, the standard motor trucks which may be readily attached to such trucks as the contractor may already own and which may be readily trans ferred from one truck to another in the event of abreakdown or the discharging of a particular truck.

As will be clear from the drawings, the

present invention comprises transverse supporting members 15 which are adjustable as at l6 to accommodate them to truck bodieslof different widths and which are adapted to be detachably secured to the sides of the truck body 12 at: 17. Upon these said supporting members 15 there is mounted a prime mover, such for'example, as a gasoline engine 18'.

Additional transverse supporting members 20, which are adjustable as at 21, are provided at the front and rear ends of the body'12 which likewise are detachably secured to the sides of the said body as at 22, and the said members are provided with bearings 23 in which are journalled the longitudinally extending shafts 24:. The said shafts are provided with aplurality of agitating paddles 25, the paddles of each shaft being preferably arranged in two series which are oppositely inclined, whereby the front series will tend to move the concrete rearwardly while the rear series would tend to move the concrete for wardly. The shafts "24 adjacent their forward ends pass through afdivision plate 26 which ex tends transversely of the vehicle body to form aforward' compartment 27 from which concrete material is excluded and in which is mounted the driving meansfor said shafts;

' These driving meansas here shown comprise sprocket wheels 28 carried by the shafts and a sprocket chain 29 engaging therewith, which 'carried by the power shaft of the motor 18;

chain also engages with a SpTOCjGt Wheel 30 A suitable clutch controlled by a clutch lever 31 may be interposed in the power line whereby the apparatus may be stopped and started atwill.

Substantially midway between the ends of the body there is provided another pair of transversely extending adjustable supporting members 35 upon whichis mounted a sprocket wheel 36. A sprocket chain 37 is trained about the said wheel and also about similar sprocket wheels 38 carried by the agi tating shafts 24;. The chain 37 isprovided with a plurality of agitating flights 39 which further serve to agitate'the concrete as it is moved toward the center of the body by the paddles 25 as above described.

The manner of employing the invention will be clear from the foregoing, it being understood that after the device has been attached to the body of the motor truck, the

said body is loaded with premixed concrete separation of the materials.

for transportation from the central plant to having agitating paddles j members; a motor also carried by said memillustrated and described it is obvious that those skilled in the art may vary the details of construction as well as the precise arrangement of parts without departing from the spirit of the invention'and therefore, it

is not wished to be limited to the above disclosure except as may be required by the claims. 7 o

What is claimed is: 1. An agitating attachment for vehicle bodies, comprising a plurality of adjustable frame members adapted to be readily attached to and detached from the body; shafts ournaled in said bers; and drivlng connections between said motor and shafts. V

2. An agitating attachment for vehicle bodies, comprlsmg a plurality of adjustable frame members adapted to be-readily' attached to and detached from the body; shafts provided with agitating paddles journaled 1n said members; a motor also carried by said members; driving connections between said motor and shafts; anda'partition plate'between said connections and paddles;

3. An agitating attachment for vehicle bodies, comprising aplurality of frame members adapted to be readily attached to and detached from the body; a longitudinally operating agitator carried by said members;

a transversely operating agitator also carried by said members; and a motor mounted on" said members for driving both of said agii ters. v In testimony whereof I aifix my signature. SAMUEL. SHAFER, J n.

tors may obviously be bought separately and applied to trucks which are already in use.

If desired the transverse agitator 39 may be omitted as it is not absolutely essential to the operation of the device.
